SHAME ON NYOU, VOX TELECOM! CAN ANYBODY HELP ME?

I am a 75-year-old Sassa handicapped pensioner and a hospital patient, having been in hospital 57 t6imes since 1997. I was with V0x from 2000 when it was since MJVN, then it became Alantic and then Vox, so I have been with the same company for 22 years. Their technical support had been marvellous. However, their manangement of the Accounts Division, quick frankly, sucks, putting their profits before plain hamnity.. I had been offered a fibre deal with then for R799, which I simply could not afford. I May, our apartment block was wired for fibre and they offered me a fibre deal for R400, which was just R6.00 more than I was presently paying Vox. I had to go for it. I phoned their Accounts Division and asked how long their notice period was. I was told a month and I need to send my cancellation email and they gave me the email address. I had two packages with them t6itally R394. At first I cancelled just the one, but on the 26th I sent a further email to them cancelled them both. Since the new fibre debit order on 1st July, 22, that meant my notice month was June, 22. My Standard Bank account was hacked into in late June and I only got it back on 1s July. I did not notice that the Vox debit order went th4rough in Ju;y and August. Horrified and having wondered why6 I was so short, I phoned them up and sent them my two cancellation emails. They pointed out that I had made a mistake with the email address, putting ***, instead o cancellations.voxtelecom.co.za. I had misheard the lady who gave me the address over the phone. I wrote to Vox, telling them how long I'd been a customers and asking them to take the email emails as being received, and sending them proof that I was a handicapped SASSA pensioner and a copy of a hospital discharge which stated I was known to them. I requested them refund me for the two months totally nearly R800. Not only did they refuse pointblank they said the I had to serve the the notice4 period of September, which would make it R1200, for service that I did not get. They said their system was worked that the end of the notice period is 1st October. What is to stop them from giving me a manual r4efune. They got 22 years of funds from me, surely they could show a little common humanity and organize a manual refund. I was shocked and horrified and disgusted by their total lack of humanity. R1200 is a fortune to me. CAN ANYONE HELP ME?????
